+.Sh NAME
+.Nm snd_atiixp
+.Nd "ATI IXP bridge device driver"
+.Sh SYNOPSIS
+To compile this driver into the kernel, place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device sound"
+.Cd "device snd_atiixp"
+.Ed
+.Pp
+Alternatively, to load the driver as a module at boot time, place the
+following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+snd_atiixp_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+bridge driver allows the generic audio driver,
+.Xr sound 4 ,
+to attach to ATI IXP audio devices.
+This driver supports 16bit playback and recording, and 32bit native playback.
+.Sh HARDWARE
+The
+.Nm
+driver supports the following audio chipsets:
+.Pp
+.Bl -bullet -compact
+.It
+ATI IXP 200
+.It
+ATI IXP 300
+.It
+ATI IXP 400
+.El
+.Sh SEE ALSO
+.Xr sound 4
+.Sh HISTORY
+The
+.Nm
+device driver first appeared in
+.Fx 6.1 .
+.Sh AUTHORS
+This manual page was written by
+.An Joel Dahl Aq joel@FreeBSD.org .
+.Sh BUGS
+The
+.Nm
+driver
+does not support S/PDIF, but implementing it should be fairly easy if the
+right hardware is available.
+.Pp
+Suspend and resume is not implemented yet.
+.Pp
+32bit recording is broken.
+Perhaps this hardware cannot do 32bit recording at all.
+If this is true, we can disable it entirely within the driver someday in the
+future.
